Abstract: ELECTRICAL CONNECTOR ATTACHABLE TO AN END PORTION OF A POWER CABLE     ABSTRACT OF THE DISCLOSURE     An electrical connector having a tubular support through which a power cable extends, and a contact housing within which the cable is connected to male or female contacts. The support and housing have mating quick threads facilitating their assembly after connection of the cable to the contacts.          A lock means on the support automatically responds to connection of the support and housing to each other, to prevent their accidental separation.  Normal operation of a cable clamping device on the support clamps and strain-relieves the cable within the support.  Deformation of the cable to offer strain relief acts upon the lock means to prevent its movement from the position in which it locks the housing and support against accidental separation.  A cable-clamping and strain-relieving device is disclosed, including a screw threadable laterally through an opening of a wiring device body into a power cable-receiving passage formed in the body.          A swiveled head on the screw bears against the insulation of the conductor.  Through the provision of guide slots in the body in which the screw is mounted, the head is maintained against rotation during advancement of the screw and removal of the screw from the body is prevented.

Abstract: INTELLIGENT TELETEXT DECODER     ABSTRACT OF THE DISCLOSURE           An equalizer and decoder system compensating for multipath distortion in digital format signals sent by teletext, for example.  The-system loads demodulated data signals and a received reference signal into a charge cou-pled device clocked in real time by a clock circuit.  Later, the reference pulse is clocked to a microprocessor-which determines tap coefficients for a transversal filter to correct the multipath distortion in the reference signal. The data signals are then applied to a transversal filter weightedwith the calculated tap weights.  After filtering, signals are decoded by the microprocessor.       In another embodiment a charge coupled device with tapped stages is used at one time for receiving the data signals in real time, and at a later time for part of a transversal filter.          In a simplest embodiment, distortions are removed by the microprocessor itself, without any separate trans-versal filter.

Abstract: ABSTRACT THERMALLY CURABLE WET-IMPREGNATED ROVINGS Thermally curable wet-impregnated rovings are disclosed in which the fibers of the roving are impreg-nated with a liquid polyepoxide having dispersed therein a latent heat-activatable epoxy curing catalyst, such as dicyandiamide, the polyepoxide dispersion having a room temperature viscosity of from 2000 to 5000 centipoises and a tack of less than about 6 on a Thwing-Albert inkometer.  The rovings are produced without organic solvent by passing a dry multifilament roving through an elevated temperature bath of the polyepoxide disper-sion, this elevated temperature being insufficient to activate the curing catalyst and functioning to lower the viscosity to enable uniform impregnation.  The wet rovings are stored in a supply package.

Abstract: MARKING APPARATUS                     ABSTRACT      A principal object of the invention is to provide an improved marking apparatus capable of clearly marking desired information at the same relative location on a succession of rapidly-moving, heat-sensitive articles.  Prior art marking devices employing heated printing heads presented problems when employed to mark in this manner.  These problems became accute where the printing extended over any significant distance in the direction of travel.     The apparatus, shown generally as 10 in Figure 1 is of the type comprising an electrically-heated marking head 12, a backup means 14 positioned opposite the marking head, and means 16 for reciprocating the marking head between a withdrawn position and a marking position adjacent to said backup means.  A specific improvement according to the invention is the imparting elliptical motion of the printing head which enables contact times sufficient for clear marking at linear rates of greater than 1500 inches per minute.

Abstract: ABSTRACT A data processing machine in which the cache operating cycle is divided into two subcycles dedicated to mutually exclusive operations.  The first subcycle is dedicated to receiving a central processor memory read request, with its address.  The second subcycle is dedicated to every other kind of cache operation, in particular either (a) receiving an address from a peripheral processor for checking the cache contents after a peripheral processor write to main memory, or (b) writing anything to the cache, including an invalid bit after a cache check match condition, or data after either a cache miss or a central processor write to main memory.  The central processor can continue uninterruptedly to read the cache on successive central processor microinstruction cycles, regardless of the fact that the cache contents are being "simultaneously" checked, invalidated or updated after central processor writes. After a cache miss, although the central processor must be stopped to permit updating, it can resume operations a cycle earlier than is possible without the divided cache cycle.
